Outer envelope membranes from chloroplasts are isolated as right-side-out vesicles [PDF]
, 1992 Outer envelope membranes were isolated from purified chloroplasts of pea leaves. The sidedness of the vesicles was analyzed by (i) aqueous polymer-two phase partitioning, (ii) the effect of limited proteolysis on the outer-envelope proteins (OEP) 86 and ...

Membrane vesicles in magnetotactic bacteria
Microbiological Research, 2003 Magnetotactic bacteria are microorganisms that respond to magnetic fields. We have studied the surface ultrastructure of Magnetospirillum magnetotacticum and uncultured magnetotactic bacteria from a marine environment using transmission electron microscopy and freeze-etching.

Mechanism of cellular uptake of genotoxic silica nanoparticles. [PDF]
, 2012 Mechanisms for cellular uptake of nanoparticles have important implications for nanoparticulate drug delivery and toxicity. We have explored the mechanism of uptake of amorphous silica nanoparticles of 14 nm diameter, which agglomerate in culture medium ...

Human Vaccines & Immunotherapeutics, 2012 Nowadays adjuvants are extensively used as immuno-stimulatory and immuno-modulatory compounds as components of subunit and combination vaccine formulations. The adjuvants of microbial origin are more frequently used among currently used licensed or experimental adjuvants.

Uptake of Ca2+ by isolated secretory vesicles from adrenal medulla [PDF]
, 1982 Intact secretory vesicles isolated from bovine adrenal medulla contain 94 nmol Na+ per mg of protein, and Ca2+ influx into the vesicles is inhibited by increasing concentrations of extravesicular Na+ (but not of K+, Li+ or choline+) or by addition of the

Synthetic phospholipid vesicles containing a purified viral antigen and cell membrane proteins stimulate the development of cytotoxic T lymphocytes [PDF]
, 1979 Synthetic phospholipid vesicles (liposomes) containing the purified glycoprotein (G) of vesicular stomatitis virus (VSV) and solubilized membrane proteins from cells of the appropriate H-2 haplotype elicited H-2-restricted cytotoxic T lymphocytes (CTL ...
